But that's my question, really. At high speed, I actually find the ability to modulate the PCCBs better than the Iron rotors that I had on my '16 Spyder, and a lot of the pro drivers have said they prefer the PCCBs on the track as well. I'm curious if there are people who have tracked both extensively found anything they didn't like about them, other than the cost.

They're fantastic.
The fact that you get larger calipers to insert larger rotors is already a win, even if you track. Just remove the CCB, and replace w irons. On the 997's you get additional cooling duc work, bigger calipers, different hubs and "bigger" master cylinder- win /win/win / win over standard.

p.s.
You lads are missing some crucial information about the PCCB. The damping alone is a huge difference. The steering feel. I currently have the irons on my car, but my car came w/ pccb. Massive difference in steering and when the car is moving - the feedback the car gives.If i could afford $20k a year on brakes i would have PCCB.

Don't know anyone who does more than four days a year who uses PCCBs on the track. Hold, I know one guy. He just killed a rear rotor and cost him $6k to fix.

Right, now with some companies refurbishing the rotors I would consider PCCB, but its not really proven yet.
I can always throw steel rotors on.

All the best drivers I know love PCCB.

Then again, we're all trying to figure out how to cram 19" on the car so we can run faster tires....

But the best iron rotors aren't made in that size and I've yet to meet someone at the track who felt the 380's with proper pads/fluid were not beyond reproach...

With the standard Red calipers, you can always use the stock 380's or add spacers and use the larger 410 rotors (including carbon-ceramic).

But with the PCCB Yellow calipers, you are stuck using the larger ones (which weigh a ton in iron)...

They don't have to pay for replacements and/or maintenance; normal track junkies have to.

Ergo: invalid argument presentation.

^ It's valid; the discussion is whether PCCBs are preferred, cost aside.

Non-PCCBs also provide the ability to get smaller wheels (19s). PCCBs cost is too high. If they came down by 50%+ I might consider them.

You can get 19"s that fit on PCCBs - HRE makes them and I think Forgeline might too. You should be able to run the new 488 Challenge slicks (ignoring the Porsche warranty issue) which are 275/675-19 fr and 315/705-19 rear. Both are approx 3% smaller diameter than the stock fitment for the RS, but I don't see that being an issue.

I guess you missed the part of my question where I said cost aside...

I love the PCCBs. The bite is great, the steering feel is great, no brake dust, don't have to change pads, no squeal - but this is a 3-4 day a year track car. For serious track work, I would go to iron.

ExMB

No I didn't. You are asking for a compare of the same car with different brakes evaluated by the same same person and then mention the preference of pro drivers who don't have to worry about that cost aspect. Your question/answer is hypothetical since the requirement you are asking about can virtually only be met by testers supported by outside finances or those with money who don't care.

...or somebody who will not track enough...or keep the car long enough...to go through a set of ceramics.

True we do have a 19" option which clears PCCB's but we only suggest it for track use only. Clearance between the caliper and the inner barrel is so fine that any debris that gets caught in the right spot will score the inner barrel of the wheel (if it's a rock for example). Most common to see is tire clag getting stuck on the barrels, but it's still a liability worth knowing about.
